On the relationship between the magnetic and VLF signatures of the substorm expansion phase
Read more of: On the relationship between the magnetic and VLF signatures of the substorm expansion phaseWe firmly establish a certain class of post-midnight ELF/VLF wave events as a signature of the substorm expansion phase. These substorm chorus events (SCEs) have been observed near L = […]

Lithostratigraphy of Miocene–Recent, alkaline volcanic fields in the Antarctic Peninsula and eastern Ellsworth Land
Read more of: Lithostratigraphy of Miocene–Recent, alkaline volcanic fields in the Antarctic Peninsula and eastern Ellsworth LandMiocene–Recent alkaline volcanic rocks form numerous outcrops scattered widely throughout the Antarctic Peninsula and eastern Ellsworth Land. They occur mainly as short-lived (typically 1–2 million years) monogenetic volcanic fields but […]

Feasibility of an airborne TV camera as a size spectrometer for cloud droplets in daylight
Read more of: Feasibility of an airborne TV camera as a size spectrometer for cloud droplets in daylightPhotographs of clouds taken with a camera with a large aperture ratio must have a short depth of focus to resolve small droplets. Hence the sampling volume is small, which […]
